A sweet blend of classic Pro-tec styling and Pro-tec's revolutionary multi-impact SXP Liner technology, the B2 destroys all others in fit and style. SXP certified liners are constructed from patented multi-impact material that is ideal for aggressive riding styles. Multi-impact SXP liners have built in rebound control. Once the liners have been compressed, multi-impact SXP memory kicks in and the liner rebounds, maintaining its impact absorbing qualities. Ageless flare and three different ABS shell sizes make the B2's fit unrivaled while the stainless hardware, soft tubular webbing straps, and signature sticker packs provide the perfect blend of proven performance and style. Shred hard and live easy.
